Apparently, some people don't understand the "Investigation" part of "Federal Bureau of INVESTIGATION." 

Meet Dominick Pelletier.  While being interviewed for a job with the FBI, he admitted that he had child pornography on his home computer.  Not only did he not get hired, he would up with 80 months to serve in a federal prison without parole.  The dry opening of the Court of Appeals opinion is priceless: 

Federal investigative agents will tell you that some cases are hard to solve. Some cases require years of effort—chasing down false leads and reigning in flighty witnesses. Others require painstaking scientific analysis, or weeks of poring over financial records for a hidden clue. And some cases are never solved at all—the right witness never comes forward, the right lead never pans out, or the right clue never turns up.

This is not one of those cases. The defendant, Dominick Pelletier, admitted during a job interview with the FBI that he had pornographic pictures of children on his home computer. Instead of joining the FBI’s vaunted ranks, Pelletier was indicted for one count of possession of child pornography. After the district court denied two of his motions to suppress, Pelletier entered a conditional guilty plea and reserved the right to appeal the denial of the suppression motions. Finding no error, we affirm.

The lesson here is:  if you have child porn on your computer, don't tell anyone.  And especially don't tell the FBI.
